The Accord Hybrid has standard Collision Mitigation Braking System, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Sonata Hybrid offers an available collision warning system without the automated brake feature which would prevent or reduce the collision if the driver fails to react.
